Someone had suggested Willy Taco, so after a soccer game, a bunch of the team and parents went. It was packed, but they were not phased at all by our big group on a Friday night. Very upbeat, happy, helpful staff! You can tell they love working there. Place has a really cool vibe.
Great menu...hard to choose. Tacos are call about $3-$4 each. All kinds of amazing, creative choices. Mexican street corn...awesome. (Just maybe needs a touch of limón mayonesa.) Best guacamole I've ever had. Awesome blue chips.
I'd drive to Spartanburg just to eat there.
